Matthew Henry Commentary Jeremiah 49:34-39

"The word of Jehovah that came to Jeremiah the prophet concerning Elam, in the beginning of the reign of Zedekiah king of Judah, saying, Thus saith Jehovah of hosts: Behold, I will break the bow of Elam, the chief of their might. And upon Elam will I bring the four winds from the four quarters of heaven, and will scatter them toward all those winds; and there shall be no nation whither the outcasts of Elam shall not come. And I will cause Elam to be dismayed before their enemies, and before them that seek their life; and I will bring evil upon them, even my fierce anger, saith Jehovah; and I will send the sword after them, till I have consumed them; and I will set my throne in Elam, and will destroy from thence king and princes, saith Jehovah. But it shall come to pass in the latter days, that I will bring back the captivity of Elam, saith Jehovah." — Jeremiah 49:34-39 (ASV)

The Elamites were the Persians. They acted against God's Israel and must be reckoned with. Evil pursues sinners. God will make them know that He reigns. Yet the destruction of Elam will not be forever. But this promise was to have its full accomplishment in the days of the Messiah.

In reading the divine assurance of the destruction of all the enemies of the church, the believer sees that the outcome of the holy war is not in doubt. It is blessed to remember that He who is for us is more than all that is against us. And He will subdue the enemies of our souls.
